GEORGE W. BROWN, OF MAYNARD, IMASSACHUSETTS.

FOUNTAIN-'SYRINGE.

To all whom it may concern:

Be it known that I, GEORGE W. BRowN, a citizen of the United States,residing at Maynard, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inFountain-Syringes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will en ableothers skilled in the art to which it appertains to make and use thesame.

A fountain syringe consists of a suitable water receptacle usually offlexible material such as rubber. a delivery tube leading therefrom alsousually of flexible rubber, and a nozzle at the free end of the tube. Inusing the apparatus it is a common practice to fill the receptacle at afaucet and then hang up the receptacle at a suitable height so as togive suflicient head to cause the water to flow freely from the nozzle.Unless considerable care is taken in filling the receptacle only to theproper height and also in the manipulation of the receptacle after it isfilled, more or less water collects on the outside of the receptacle orslops over the top, so that careful and thorough wiping of thereceptacle and delivery tube is necessary before the apparatus can beused with safety and comfort. Also, owing to the flexible character ofthe receptacle, water is sometimes slopped over the top by accidentalagitation of the receptacle while the apparatus is in use.

The object of the present invention is to do away with the inconvenienceand discomfort occasioned by the water deposited on the receptacle of afountain syringe during filling, or which slops over the top of thereceptacle as it is being hungup or while the apparatus is in use.

With this object in View the invention contemplates the provision of asuitable drip cup on a portion of the delivery tube which is verticalwhen the apparatus is in use. said drip cup having its open end directedupwardly so as to receive any water running down the outside surface ofthe receptacle and prevent this water from continuing along the tube tothe vicinity of the nozzle.

The provision of this drip cup affords pro- Specification of LettersPatent.

tection against the carelessness 0r incompetency of a nurse in preparingthe apparatus for use, and efiectually prevents any serious orinconvenient results in case of an accidental or other agitation of thereceptacle. The drip cup may be of any suitable material. Preferably,however, the drip cup is of yielding material such as rubber and isshaped to closely surround the delivery tube. To enable the tube to befirmly gripped by the'cup without being constricted or collapsed, thetube is provided with a section of rigid material such as glass, uponwhich the drip cup is mounted.

The present invention will be clearly understood from an inspection ofthe accom panying drawing, in which;

Figure l is a view in front elevation of a fountain syringe embodyingthe invention in its preferred form; and Fig. 2' is a detail sectionalview of the rigid section of the delivery tube with the drip cup mountedthereon.

In the drawing, 1 indicates a rubber bag forming the fountain of thesyringe, 2 the delivery tube of the syringe, and 3 the nozzle. Asindicated in th drawing, the delivery tube is made in three sections,the upper and lower sections being of flexible rubber, and theintermediate section 4 being of rigid material such as glass, or hardrubber. The intermediate section 4; is so located that when theapparatus is in use this section lower end tightly gripping the section4 and having its open upper end directed upward toward the bag 1. Sincethe drip cup is located on a portion of the delivery tube which standsin a vertical position when the apparatus is in use, it receives andholds any water running down the tube from the outer surface of the bag1 and prevents this water from passing farther down the tube 211dcausing any inconvenience or discomort.

The nature and object of the invention having been indicated, and apreferred embodiment of the invention having been speei cally described,what is claimed is,

A fountain syringe, having, in combination of rigid material having itsopen end tion, a Water receptacle, a delivery tube directed toward thereceptacle. leading therefrom consisting of sections of flexiblematerial: and an intermediate section GEORGE BROWN 5 of rigid materialwhich is vertical when the Witnesses:
